Abstract
Description
Technical Field
[0001] This utility model belongs to the field of jujube kernel grinding technology, specifically relating to a jujube kernel shelling and grinding device. Background Technology
[0002] Before grinding jujube kernels into powder, they need to be shelled first. After drying, the shelled jujube kernels can be ground into powder using a jujube kernel grinding device. Current grinding devices use a high-speed rotating grinding disc inside, which works in conjunction with a toothed outer frame to grind the kernels. During this process, the ground jujube kernels are discharged through a filter screen below. However, as more jujube kernels are added, they directly enter the internal space of the grinding disc. The jujube kernel particles in this grinding space need to be ground over a certain period to gradually become smaller particles and then powder. Both whole and large jujube kernel particles are driven to rotate at high speed by the grinding disc, constantly impacting the inner wall of the space and the filter screen. Unlike the thick walls of high-hardness equipment, the filter screen is a thin, perforated plate with a suspended center. When impacted by whole and large jujube kernel particles, it is susceptible to damage and deformation, affecting the filtration effect on the jujube kernel powder. Furthermore, the high hardness of jujube kernels further exacerbates the risk of filter screen deformation. Utility Model Content
[0003] This utility model provides a jujube kernel shelling and grinding device, which can efficiently perform preliminary processing of jujube kernels, so that whole kernels and large kernels will not enter the space corresponding to the filter screen position, thus avoiding damage or blockage of the filter screen caused by collision or compression of whole kernels or large kernels under high-speed movement.
[0004] This utility model provides the following technical solution: a jujube kernel shelling and grinding device, including a grinding mill equipment box body, a drive shaft installed on one side of the grinding mill equipment box body, a frustum-shaped inner grinding block fixedly connected to one end of the drive shaft, a frustum-shaped grinding groove opened on one side of the frustum-shaped inner grinding block, a sealing plate provided on one side of the frustum-shaped inner grinding block, a frustum-shaped insert grinding block fixedly connected to the inner wall of the sealing plate, the frustum-shaped insert grinding block extending into the frustum-shaped grinding groove, an outer sealing frame detachably connected to one side of the grinding mill equipment box body, an inner protrusion fixedly connected to the inner wall of the outer sealing frame, a filter screen inserted into the inner wall of the outer sealing frame, and a grinding disc installed on the outer wall of the drive shaft.
[0005] The grinding mill equipment box body is fixedly connected to a connecting plate on one side, and the outer enclosure frame is bolted to the connecting plate.
[0006] The inner wall of the frustoconical grinding groove is fixedly connected with inner groove wall grinding teeth, and the outer wall of the frustoconical inner grinding block is fixedly connected with outer inclined grinding teeth.
[0007] The sealing plate is fixedly connected to a feed pipe on its outer wall, and the feed pipe passes through the frustum-shaped insert grinding block.
[0008] The outer wall of the frustoconical insert grinding block is fixedly connected with insert grinding teeth, which cooperate with the grinding teeth on the inner groove wall.
[0009] The inner wall of the inner protrusion is fixedly connected with a mating grinding tooth, which mates with the outer inclined grinding tooth.
[0010] The bottom end of the outer enclosure frame is fixedly connected to a discharge pipe, which corresponds to the position of the filter screen.
[0011] The beneficial effects of this utility model are as follows: By utilizing the inner wall of the frustum-shaped grinding groove, the outer wall of the frustum-shaped inserting grinding block, and the outer wall of the frustum-shaped inner grinding block and the inner wall of the inner protrusion to form a grinding channel with gradually narrowing gaps, the shelled jujube kernels can be initially processed into small particles. The narrow outlet of the grinding channel filters out large jujube kernel particles, preventing whole or large jujube kernel particles from entering the space corresponding to the filter screen. This avoids damage or blockage of the filter screen caused by collisions or compression of whole or large jujube kernel particles under high-speed movement. Furthermore, the tortuous distribution of the channel can form a longer grinding channel within a limited space, thus enabling more efficient initial processing of jujube kernels.
[0012] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0018] Please see Figures 1-4 This utility model provides the following technical solution: a jujube kernel shelling and grinding device, including a grinding mill equipment box body 1, a drive shaft 2 installed on one side of the grinding mill equipment box body 1, a frustum-shaped inner grinding block 21 fixedly connected to one end of the drive shaft 2, a frustum-shaped grinding groove 22 opened on one side of the frustum-shaped inner grinding block 21, a sealing plate 3 provided on one side of the frustum-shaped inner grinding block 21, a frustum-shaped insert grinding block 31 fixedly connected to the inner wall of the sealing plate 3, the frustum-shaped insert grinding block 31 extending into the frustum-shaped grinding groove 22, an outer sealing frame 4 detachably connected to one side of the grinding mill equipment box body 1, an inner protrusion 41 fixedly connected to the inner wall of the outer sealing frame 4, a filter screen 42 inserted into the inner wall of the outer sealing frame 4, and a grinding disc 5 installed on the outer wall of the drive shaft 2.
[0019] In this implementation scheme: After the filter screen 42 is installed in the locking groove on the inner wall of the outer closed frame 4, the outer closed frame 4 is installed on the side wall of the connecting plate 11. Then, the sealing plate 3 is rotated and closed on one side of the outer closed frame 4. The drive shaft 2 drives the frustum-shaped inner grinding block 21 and the grinding disc 5 to rotate in the internal space of the outer closed frame 4 under the action of the drive motor. The worker adds the shelled jujube kernels into the feed pipe 32. The jujube kernels enter the frustum-shaped grinding groove 22 and are crushed under the action of the inner groove wall grinding teeth 23 and the insert grinding teeth 33. They enter the corresponding positions of the outer inclined grinding teeth 24 and the mating grinding teeth 43, and are ground again by the outer inclined grinding teeth 24 and the mating grinding teeth 43. The jujube kernels ground into small particles enter the grinding range of the grinding disc 5. The grinding disc 5 and the outer closed frame 4 cooperate to perform the final grinding of the small particles of jujube kernels. After grinding, the jujube kernel powder that reaches the discharge diameter is discharged through the filter screen 42 and the discharge pipe 44. During the initial grinding process, the inner groove wall grinding teeth 23 and the insert grinding teeth 43... While the grinding teeth 33, the outwardly inclined grinding teeth 24, and the mating grinding teeth 43 perform preliminary grinding of the jujube kernels, the inclined inner wall grinding teeth 23, the insert grinding teeth 33, the outwardly inclined grinding teeth 24, and the mating grinding teeth 43 apply force to the jujube kernel particles, squeezing and conveying them to the rear of the channel. The grinding channel with gradually narrowing gaps is formed by the cooperation of the inner wall of the frustum-shaped grinding groove 22, the outer wall of the frustum-shaped insert grinding block 31, the outer wall of the frustum-shaped inner grinding block 21, and the inner wall of the inner protrusion 41. This allows the shelled jujube kernels to be preliminarily processed into small particles. The tortuous distribution of the channel can form a longer grinding channel in a limited space, allowing for more efficient preliminary processing of the jujube kernels. This prevents whole or large jujube kernel particles from entering the space corresponding to the filter screen 42, avoiding collisions or compression of the filter screen 42 under high-speed movement, which could damage or clog the filter screen 42. This improves the efficiency and effectiveness of the equipment in discharging jujube kernel powder.
[0020] A connecting plate 11 is fixedly connected to one side of the main body 1 of the grinding mill equipment box, and the outer enclosure frame 4 is bolted to the connecting plate 11. The connecting plate 11 facilitates the installation of the outer enclosure frame 4. The outer enclosure frame 4 is connected to the connecting plate 11 by bolts, so that the staff can remove the outer enclosure frame 4 and inspect the internal components of the outer enclosure frame 4.
[0021] The inner wall of the frustoconical grinding groove 22 is fixedly connected with inner groove wall grinding teeth 23, and the outer wall of the frustoconical inner grinding block 21 is fixedly connected with outer inclined grinding teeth 24; by setting the inner groove wall grinding teeth 23 and the outer inclined grinding teeth 24, the jujube kernel can be ground and crushed.
[0022] The outer wall of the sealing plate 3 is fixedly connected to the feed pipe 32, which passes through the frustum-shaped insert grinding block 31. The feed pipe 32 serves to feed materials, and there is a large gap between the discharge end of the feed pipe 32 and the inner wall of the frustum-shaped grinding groove 22 to facilitate the smooth discharge of raw materials.
[0023] The outer wall of the frustoconical insert grinding block 31 is fixedly connected with insert grinding teeth 33, which cooperate with the grinding teeth 23 on the inner groove wall; by setting the insert grinding teeth 33, it can cooperate with the grinding teeth 23 on the inner groove wall to grind jujube kernels.
[0024] The inner wall of the inner protrusion 41 is fixedly connected with a mating grinding tooth 43, which mates with the outer inclined grinding tooth 24; the mating grinding tooth 43 and the outer inclined grinding tooth 24 are positioned to grind the jujube kernel.
[0025] The bottom of the outer enclosed frame 4 is fixedly connected to a discharge pipe 44, which corresponds to the position of the filter screen 42; by setting the discharge pipe 44, the jujube seed powder can be discharged in a tilted manner.
[0026] The working principle and usage process of this utility model: Driven by a drive motor, the drive shaft 2 drives the frustum-shaped inner grinding block 21 and the grinding disc 5 to rotate within the inner space of the outer enclosed frame 4. The worker adds the shelled jujube kernels into the feed pipe 32. The jujube kernels enter the frustum-shaped grinding groove 22 and are crushed by the grinding teeth 23 on the inner groove wall and the interlocking grinding teeth 33. They then enter the corresponding positions of the outwardly inclined grinding teeth 24 and the mating grinding teeth 43, where they are further ground. The ground jujube kernels, now in small particles, enter the grinding range of the grinding disc 5. The grinding disc 5 and the outer enclosed frame 4... The small jujube kernels are then ground to a final size. The jujube kernel powder that reaches the discharge diameter is discharged through the filter screen 42 and the discharge pipe 44. The grinding channel with gradually narrowing gaps is formed by the cooperation of the inner wall of the frustum-shaped grinding groove 22, the outer wall of the frustum-shaped insert grinding block 31, the outer wall of the frustum-shaped inner grinding block 21, and the inner wall of the inner protrusion 41. The shelled jujube kernels are initially processed into small particles. Whole particles and large particles of jujube kernels will not enter the space corresponding to the position of the filter screen 42, so as to avoid the whole particles or large particles of jujube kernels colliding or squeezing the filter screen 42 under high speed, which would damage or clog the filter screen 42.
